To all whom t may concern.'

Be it known that l, Moms Lowa', a citizen of the United States, and resident of the city or" New York, in the county oi Kings and State of New York, have invented certain new and useful lmprovements in Corner Fastenings for Bedsteads, of which the following is a specification.

The present invention relates to improvements in corner-fastenings for bedsteads, and has for'its main object to provide a simple, efficient and durable device of this type which is made by stamping operations.

Another object of the invention is to procuce a corner-fastening of the type specined, which permits of a convenient assembling of the bed and of a taking down .of the lsame by inexperienced operators with but little time and energy.

A further object of the invention is to so construct the corner-fastening .that the bed-bottom supporting member may be clamped thereto or released therefrom by an element that forms part o' the corner- Jfastening, there being thus no chance oi." losing or misplacing the clamping member.

A still further object ot the invention is to so construct the corner-fastening that the bed-bottom supporting angle bar may be reversibly secured thereto, so -as to adapt it to ordinary `spring mattresses and also to box springs.

`With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arraiigie-A ment and construction of parts hereinafter in the appended 1 claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and priop'ortion of the several parts and details of construction within the scope of the appended claims, `without departing trom spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention vis illustrated in the accompany-ing drawings, in 'which :-d

Figure 1 is a perspective vview of a por'- tion of the` corner-post of a bedst'ea'd, with a corner-fastening, constructed in accordance with the present invention, in position thereon, the bed-bottom supporting angle bar being shown in position to receive lan ordinary spring mattress; Fig. 2 is a side lFrom elevation of thel elements shown in Fig. 1 Fig is a section taken on line 3-3 of Fig. 2; Fig. 4 is a section taken on line 4 of j Fig. 2; Fig. 5 is a plan view, partly in section, of the corner-iastening, showing the` bed-bottom supporting angle bar positioned` to receive a box spring;-v

Fig. 6 is a perspective view'oit one of the ends otthe angle bar; Fig. 7 is a plan view otr the blank oit which the shell of the'tastening is made.

In the drawings, the numeral 10 indicates a portion of a rectangular cornerq post of a bedstead, to which the cornerfastening is to be attached. The cornertastening includes abracket-like hollow rectangular shell 11, preferably, made of one integralpiece, or'instance, by stamping operations from a blank l2, shown in Fig. 7 oi the drawings-- This shell includes a top wall 13, an inner side wall 14, an outer side wall-15, from whichextends inwards,

toward the wall 14,` a bottom portion 16. l the said bottom portion rises a 'plate member 17, the 4upper section of which is inclined, as shown at 18, said inclined portion extending towardthe upper edge of `the outer side wall 15. The elements et the shell soV ,tar described extend longitudinally of the bedstead, that is to vsay at right angles to the longitudinal axis of the corner post 10, and Vserve to receive, in ka mannerhere'inaiter to be described, the bed bottom supporting angle bar 19. T he shell includes furthermore end members y20,'one of which engages the corner-post, while the other abutsiagainst the rst-mentioned end member. substantial distance below the bottom. portion 16 above referred to, screw bolts 21, passing through the. said endv members into.

The' end members project a the corner-post, serving toattach the shell to thefsaid post. The inner endwall `14 rextends down to the lower edge oi one o the :end members20, tov malte the ccnstruction as rigid. as possible.

The shell, as described, constitutes 'a hollow rectangular body, adapted to receive one end of the kangle bar 19. Adjacent its end, the iiange 22 of the angle bar is partly cut off, as. shownat 28, there being anfoblong piece removed, the length of which ycorresponds substantially to that of the top wall 18 oi? the shell 11, while its width is somel` what less `than the height ci. thev flange 22, hus leaving a strip 2a-on the flange adjavlength of the top 13 of the shell. This arpermits of inserting the angle rangement In one bar into the shell in two positions.

of the positions, shown in Figs. 1 to 4, in-` clusive, the flange 26 constitutes the horizontal flange of the angle bar, the other flange, denoted by the numeral 22, being disposed vertically and below the flange 26. lVhe-n so inserted, the flange 26 abuts against the inner face of the top wall of the shell and the strip 24 against the inner face of the outer side wallV 15 of the shell. .ln the other position, shown in Fig. 5 of the drawings, the flange 26 forms the vertical flange of the angle bar and the flange the horizontal flange, the cut out portion 23 being provided to permit of an insertion of the angle bar in this manner. rlhe inwardly bent portion 27 of the flange 26 projects in this position toward the inclined portion 18 of the plate member 17, for a purpose hereinafter to be described.

The plate member 17 and its inclined portion 18 are capable of yielding, constituting thus a aw that is adapted to be forced against the angle bar 19. For effecting this clamping operation, there is a lever 28 pivoted to the shell 11, the pivot being in the .form of a screw bolt 29, that extends through the inner wall 14 of the shell and through the plate member 17. The lever is provided with a side cam face 30, adapted to co-operate with a lug 31, formed upon the plate member 17. The lever is furthermore provided with an end cam face 32, capable of co-operating with the flange 26 of the angle bar 19. The two cam faces mentioned are on a vertically extending section 33 of the lever, the latter being provided with a horizontally extending handle portion 34. A spacing element 35, in the form of a sleeve, is drawn over the screw bolt 29, it serving to hold the said lever in proper relation to the lug A31.

The two shells 1.1 on the cojrner-posts, form` ing an end member of the bedstead, may be connected in any suitable manner, for instance by an angle bar 36, which is fastened by screws 37, or otherwise, to lugs 38, the latter being', preferably, made integral with the two shells.

The operation of the corner-fastening is as follows: lf the bedstead 'is to be provided with an ordinary spring mattress, the angle bars 19 are inserted into the shells in the manner indicated in Figs. 1 to 4, inclusive, of the drawings, in which the flanges 26 of the said bars are disposed horizontally in contact with the top walls 13 of the shells. ln order to permit of such insertion, obviously, the lever 28 must be moved in the outer face of said angle bar nasale? direction of the arrow shown in Fig. 2 of the drawings, so as to disengage its side cam face from the lug 31 and to bring the cam face 32 to a distance from the top wall of the shell sufficient to permit of convenient insertion of the angle bar. After the angle bar has been put into place, the lever is shifted into the position shown in Figs. 1 to 1, inclusive, of the drawings, whereby the inclined portion 18 of the plate member 17 is forced against the strip 24 of the angle iron, thereby clamping the latter against the outer side wall 15. Simultaneously therewith, the end cam face of the lever clamps the flange 26 of the angle bar against the top wall 1.3 of the shell. lf it is intended. to remove the angle bar from the shell, the lever 28 is disengaged from the flange 26 of the angle bar, whereby the yielding portion of the shell is permitted to recede from the ano'le bar.

ff it :is desired to use a box spring on the bedstead, the angle bar must be reversed, that is to say it must be brought into the position shown in Fig. 5 of the drawings, in which the flange 26 extends vertically, it being in abutment with the outer side wall 15 of the shell. The lever 28 is then forced into clamping position, it causing thefportion 18 of the wall 17 to grip the inwardly bent section 27 of the angle iron bar. The cam face 32 on the said lever does not function in this case. llt is to be observed, however, that, inasmuch as the portion 18 of the plate member 17 is inclined, it has a tendency to clamp the angle bar against the top wall 13 and the outer side wall 15 of the shell. The plate member 17, lever 28, bolt 29 and spacing element 35 do not interfere with the insertion of the angle bar, by reason of the latter being provided with the cut off portion 23.

ft is obvious that, while herein the shell has been described. as made of one integral piece by stamping operations, the same may be otherwise produced, without departing from the invention.
